Most researchers define small group as an alliance having at least three and no more than twelve or fifteen members. A group needs to have at least three members; otherwise it would simply be a said. Therefore, at least three members are required to form a small group. Too many members in a group (more than twelve or fifteen members) inhibit the group members’ ability to communicate with each other. Such a group must have a common purpose or goal and the members work together to achieve that goal. This type of communication refers to interactions among three or more people who are connected through a common purpose, mutual influence, and a shared identity. Small groups are important communication units in academic, professional, civic, and personal contexts.
However, an ideal small group should possess the following three elements:
Size: A small group must have at least three members and no more than twelve or fifteen members.
Interaction: The members of small group can exchange their views freely and liberally with each other.
Goal: Every small group must have a common purpose or goal and the members work together to achieve that goal.
